He's one of only five actors to have worked in both the Witcher live action show and video game series, the other four being Jaroslaw Boberek, Miroslaw Zbrojewicz, Wojciech Duryasz and Michal Piela. Unlike the other three, Szczesny also worked in the audio book series, where his roles included Yarpen Zigrin (played by Boberek in the show and games).
